I think i was in the process of doing a guide at one point. I'll see if i have any pictures of the repair.

[DD-Indeed]

Thanks for the info, I'll check the fan and buy a computer fan for replacement. But, it would be good to have that guide, if there is one.

From memory, you need a little 25mm fan, and 12v is available to supply it across the two outer pins of the original fan once you've removed it.

The outer pins give about 6V from memory which works well as the fan runs reliably at slow speed so is nice and quiet.

Update!

The small fan in the panel works, so that can be counted out of the possible faults. Here's a video of it, turned the key to II-position and then off:

And, I checked those VAC-lines on the engine bay. There was couple hoses, that were in wrong places. But, now they are in correct position, thanks to the images you have here, but I'm not yet gone for a drive, so I'll tell more later on, that did it affect anything.

[DD-Indeed]

Drove back to home with longer route than usually, to lift the engine temperature to normal. The fault still occured.

But, I noticed something. One servo was making a long sound, when I dropped the temperature from HI to 27īC and I did hear a very quiet sound of something moving. And I believe, that it was the flap, that controls the airflow direction between the two routes: going throught the heater matrix <---> passing it.

So, could it be, that it's not working propely and it moves fully from one side to another, when I adjust the temp between LO-27`C and HI ?

[DD-Indeed]

Anyone ? Is this common and/or repairable problem ?

What you report would be consistent with the climate panel thinking the car is hotter than it really is. I.e. there's a transition from full cooling to full heating between 27 and HI, and what you are hearing is the blending flap moving across its' full travel. Air direction between the floor, defrost and face vents also changes depending on whether the system is heating or cooling, so I think that aspect is normal.

You can see the temperature probe outputs in the live data using a tech 2. I appreciate you're a little far away, but if you can get it to someone with a Tech 2, that would shed some more light on the problem, I'm sure.

Thank you for this! And yea, here is couple members on the Opel Club Finland, who has those readers, but even they are long away from where I am. But I'll try to get my hand on one of those readers.

And what can I do with that reader, does it show, if there is something wrong or can it do reprogramming in case, that there is issues with that panel's ecu ?
